Internet Archive lets you play one of the earliest computer games Space War! emulated in JavaScript in the browser.

This entry covers the historical context of Space War!, and instructions for working with our in-browser emulator. The system doesn’t require installed plugins (although a more powerful machine and recent browser version is suggested).

The JSMESS emulator (a conversion of the larger MESS project) also contains a real-time portrayal of the lights and switches of a Digital PDP-1, as well as links to documentation and manuals for this $800,000 (2014 dollars) minicomputer.

Number 1 and Benford’s Law - Numberphile (by numberphile)

I’d heard of Benford’s Law before but it sounded totally counter intuitive to me. This video does a good job explaining why one shows up as the leading digit in sets of random numbers that span large ranges.

(via Descriptive Camera)

A digital camera sends photos to Mechanical Turk service to generate a textual description and print the result on a thermal printer.  Thus a camera that prints out a textual description of what you photographed.

Blackmail DRM - Stolen Thoughts

2012 Feb 13, 4:00

Most existing DRM attempts to only allow the user to access the DRM'ed content with particular applications or with particular credentials so that if the file is shared it won't be useful to others. A better solution is to encode any of the user's horrible secrets into unique versions of the DRM'ed content so that the user won't want to share it. Entangle the users and the content provider's secrets together in one document and accordingly their interests. I call this Blackmail DRM. For an implementation it is important to point out that the user's horrible secret doesn't need to be verified as accurate, but merely verified as believable.

Apparently I need to get these blog posts written faster because only recently I read about Social DRM which is a light weight version of my idea but with a misleading name. Instead of horrible secrets, they say they'll use personal information like the user's name in the DRM'ed content. More of my thoughts stolen and before I even had a chance to think of it first!

URI Percent Encoding Ignorance Level 0 - Existence

2012 Feb 10, 4:00

As a professional URI aficionado I deal with various levels of ignorance on URI percent-encoding (aka URI encoding, or URL escaping). The basest ignorance is with respect to the mere existence of percent-encoding. Percents in URIs are special: they always represent the start of a percent-encoded octet. That is to say, a percent is always followed by two hex digits that represents a value between 0 and 255 and doesn't show up in a URI otherwise.

The IPv6 textual syntax for scoped addresses uses the '%' to delimit the zone ID from the rest of the address. When it came time to define how to represent scoped IPv6 addresses in URIs there were two camps: Folks who wanted to use the IPv6 format as is in the URI, and those who wanted to encode or replace the '%' with a different character. The resulting thread was more lively than what shows up on the IETF URI discussion mailing list. Ultimately we went with a percent-encoded '%' which means the percent maintains its special status and singular purpose.

Photos Bahamas Anecdote

2010 Feb 17, 8:09

Sarah and I just got back home from a Eric and Jane's wedding / Sarah and Dave's vacation trip to the Bahamas (note the lack of activity for the past twelve days on my website). I've got plenty of photos and things to post but for now I'll just relate this humorous anecdote during the rehearsal dinner. I had said something about photos to Jim, Eric's brother and he gave me a crazy look. "Oh, I thought you meant like pho-tos" he said. It took me a moment to realize he misunderstood what I said as "faux toes". I laughed until I cried a little. Also works with digital faux toes.
